As for the specific structure of the lock assembly 30 and the sensing element 40, they can be set according to the type of the lock assembly 30 and the sensing element 40 and the actual use environment. For example, the lock assembly 30 can be set to a snap-on structure, a lock tongue structure or a latch structure, and the sensing element 40 can be set to voice sensing, gesture signal or image signal, etc. These adjustments all fall within the scope of protection of the embodiment of the present application.

[0065] Below through Figures 1 to 16 The preferred embodiment of the specific structure of the lock assembly 30 and the sensing element 40 is described in detail.

[0067] In the above embodiment, the lock hook 34 is rotatably arranged on the cover head through an elastic reset member, and the lock hook 34 can be locked to the lock body 35 under the elastic force of the elastic reset member, thereby achieving the purpose of locking the cover body 20 to the shell 10. When the user needs to unlock the cover body 20, he only needs to input a sensing signal to the sensing element 40, and the driving device 31 can drive the lock hook 34 to loosen the lock body 35 according to the sensing signal, thereby achieving the purpose of unlocking the cover body 20.

[0068] The lock assembly 30 of the embodiment of the present application can achieve the purpose of opening and closing the cover body 20 through the cooperation of the driving device 31, the sensing element 40 and the elastic return member. It is easy to operate and the user does not need manual operation, thereby improving the user experience.

[0069] like Figures 1 to 9As shown, in some embodiments, the lock hook 34 is rotatably disposed on the cover body 20, and the driving device 31 includes a solenoid valve and a push rod assembly cooperating with the solenoid valve. The solenoid valve drives the lock hook 34 to release the lock body 35 through the push rod assembly.

[0070] In this embodiment, the solenoid valve can drive the push rod assembly to move up and down through the electromagnetic induction signal, so as to loosen the unlocking lock assembly 30 and open the cover body 20. Compared with the motor, hydraulic mechanism and pneumatic mechanism, the solenoid valve has the advantages of simple structure, small space occupation and fast response speed.

[0071] The base of the housing 10 has a circle of ribs around the solenoid valve mounting location to secure the solenoid valve's circumference. The base of the housing 10 also has support ribs at the solenoid valve mounting location to support the bottom of the solenoid valve. The base of the housing 10 also has a clip at the solenoid valve mounting location to secure the solenoid valve in its vertical position.

[0073] In the above embodiment, the vertical push rod 32 cooperates with the push inclined surface 321 of the lever structure 33 to convert the vertical movement of the drive device 31 into the lateral or circumferential movement of the lever structure 33, thereby enabling the push rod assembly to push the lock hook 34 in the horizontal direction to unlock the cover 20. In addition, placing the drive device 31 vertically can improve the spatial adaptability of the drive device 31 and reduce the horizontal space occupied by the drive device 31 in the household appliance 100.

[0074] like Figures 1 to 9 As shown, in some embodiments, two vertical push rods are provided, and the two vertical push rods are connected by a connecting plate 322. A T-slot 323 that cooperates with the valve stem of the solenoid valve is provided in the middle of the connecting plate 322, and two guide columns 324 are provided on both sides of the connecting plate 322.

[0075] In the above embodiment, by having two vertical push rods 32 act on the lever structure 33, the thrust balance between the vertical push rods 32 and the lever structure 33 can be improved, and the deflection of one end caused by uneven stress distribution between the vertical push rods 32 and the lever structure 33 can be reduced.

[0076] Specifically, the vertical push rod 32 has a T-slot 323 for connecting to the output of the solenoid valve to achieve vertical movement. The solenoid valve's mounting location has two guide holes that cooperate with two guide posts 324 on the vertical push rod 32 to limit its vertical movement and maintain smooth movement. The top of the vertical push rod 32 is provided with a sloped structure, which serves as a moving contact surface for pushing the lever structure 33 to rotate and open the lock hook 34.

[0077] like Figures 1 to 9 As shown, in an optional embodiment, a mounting bracket 12 is provided on the inner side of the shell, a snap-in groove 121 that cooperates with the valve body of the solenoid valve is provided in the middle of the mounting bracket 12, a limiting rib 111 that cooperates with the valve body is provided on the inner wall of the shell, and two guide sleeves 122 that cooperate with the two guide columns 324 are provided on both sides of the mounting bracket 12.

[0078] In the above embodiment, the solenoid valve is positioned and fixed by the mounting bracket 12 and the limiting ribs 111, thereby improving the operating stability of the solenoid valve and reducing the vertical displacement or left-right shaking that occurs when the solenoid valve drives the vertical push rod 32. The two guide sleeves 122 guide the two guide posts 324, achieving the effect of synchronized vertical movement of the two guide posts 324 and reducing the deflection of the two guide posts 324 during the vertical movement.

[0079] like Figures 1 to 9 As shown, in some embodiments, the input end of the lever structure 33 is provided with a pressing plate 331, the pressing plate 331 is provided with a raised button 36, the shell 10 is provided with a button hole matching the button 36, and the button 36 is exposed to the shell 10 through the button hole.

[0080] In the above embodiment, the household appliance 100 controls the automatic opening of the lid 20 by sensing signals. At the same time, the original mechanical opening structure of the household appliance 100 is retained, which is conducive to manually opening the lid of the household appliance 100 even in a power outage state, thereby improving the working reliability of the household appliance 100.

[0081] Furthermore, the pressing plate 331 is also provided with a trigger switch 332, which can send the pressing action of the button 36 to the home appliance 100, so that the home appliance 100 can adjust the corresponding cooking operation.

[0082] like Figures 1 to 9 As shown, in an optional embodiment, the output end of the lever structure 33 is provided with two spaced-apart bent levers 330 that bend toward the interior of the shell 10, and a pressing plate 331 spans and connects the two bent levers 330, and the distribution direction of the pressing plate 331 is consistent with the distribution direction of the part of the shell 10 at the key hole.

[0083] In the above embodiment, the pressing plate 331 not only provides installation space for the button 36, but also, through the cooperation of the pressing plate 331 and the two bent levers 330, evenly transmits the user's pressing force to the lock hook 34, thereby reducing the biasing force between the lever structure 33 and the lock hook 34. The two spaced-apart bent levers 330 also provide space for the button 36 to move, reducing interference between the bent levers 330 and the button 36 or the surrounding structures of the button 36.

The sensing element 40 is disposed in the housing 10 , and the housing 10 is provided with an opening to expose the sensing element 40 .

[0085] In this embodiment, the voice sensor or posture sensor only needs to sense the user's voice signal, posture signal, expression signal or touch signal. For example, the user can control the driving device 31 to drive the lock assembly 30 to unlock the cover body 20 through a nod signal or a foot lift signal. The user does not need to open the cover manually, which improves the user experience.

[0086] The voice sensor includes a microphone. The base of the housing 10 is provided with buckle holes, and buckles are provided on the left and right sides of the microphone for fixing the microphone.

[0087] like Figures 10 to 16 As shown, in some embodiments, the side wall of the housing 10 is connected to the bottom of the housing 10 through a curved surface structure 11 , and the sensing element 40 is disposed at a curved portion of the curved surface structure 11 toward the accommodation space.

[0088] In this embodiment, the sensing element 40 is disposed on the curved portion of the arc structure 11 that is bent toward the accommodation space, thereby hiding the sensing element 40 and reducing the risk of the sensing element 40 being exposed and easily damaged by accidental contact.

[0089] like Figures 10 to 16 As shown, in some embodiments, the curved portion is provided with a through hole, and the household appliance 100 further includes a placement bin 42 provided in the through hole, the placement bin 42 includes a honeycomb cover 41 located on the outside of the through hole, and an open groove 43 located on the inside of the through hole.

[0090] In this embodiment, the placement chamber 42 and the honeycomb cover 41 of the placement chamber 42 can serve to assemble and protect the sensing element 40. Moreover, the honeycomb cover 41 can also serve to receive sound, thereby improving the working sensitivity of the sensing element 40 and improving the response speed of the sensing element 40.

[0091] like Figures 10 to 16As shown, in an optional embodiment, the honeycomb cover 41 extends toward the inner side of the through hole and is located on the inner side of the shell 10, two side walls of the bottom of the open groove 43 are provided with two snap-fitting holes 431, and two side walls of the sensing element 40 are provided with two clips that are snap-fitted with the two snap-fitting holes 431.

[0092] In this embodiment, by concealing the honeycomb cover 41 inside the housing 10, the risk of damage to the honeycomb cover 41 from collisions is reduced, and the phenomenon of external dust, debris, or water adhering to and clogging the honeycomb cover 41 is also reduced. The sensing element 40 is detachably mounted to the open slot 43 by snapping, which not only facilitates the disassembly and maintenance of the sensing element 40, but also facilitates the disassembly and maintenance of the honeycomb cover 41, thereby reducing the possibility of failure of the sensing element 40 or the honeycomb cover 41.

[0093] like Figures 10 to 16 As shown, in some embodiments, the household appliance 100 further includes a pot body disposed in the accommodating space, and a locking mechanism is disposed between the pot body and the housing 10 .

[0094] In this embodiment, the locking mechanism is disposed between the pot body and the housing 10 , which can improve the spatial adaptability of the locking mechanism and reduce the cooking space occupied by the locking mechanism in the household appliance 100 .

[0095] like Figures 10 to 16 As shown, in some embodiments, the household appliance 100 includes an electric rice cooker, the shell 10 is configured as the rice cooker body, the cover 20 is configured as the rice cooker lid, and one side of the cover is rotatably connected to the rice cooker body through an elastic component 21.

[0096] In this embodiment, one side of the rice cooker lid is rotatably connected to the rice cooker body via an elastic component 21. The elastic force of the elastic component 21 allows the lid to automatically open. To unlock the lid, the user simply inputs a sensing signal to the sensing element 40. The driving device 31, in response to the sensing signal, activates the locking hook 34 to release the locking body 35. The elastic force of the elastic component 21 automatically opens the rice cooker lid. This eliminates manual operation, improving the user experience.

[0097] like Figure 1 Specifically, the rice cooker consists of a lid and a body. The body is equipped with a microphone to capture ambient sound signals. These signals are converted into electrical signals and transmitted to a control unit 50. The control unit 50 receives the sound signals and, through voice recognition technology, sends a signal to a solenoid valve to activate a lock assembly 30 to unlock the lid. The lid is rotatably attached to the body via a hinge spring. The long arm of the hinge spring is located on the lid, allowing it to be opened.

[0098] like Figure 2As shown in FIG, when the pot cover is in the closed state, the hinge spring is in a compressed state; Figure 3 As shown, when the solenoid valve drives the push rod upward to drive the lever structure 33 and the lock hook 34 to unlock, the hinge spring can bounce the pot cover open.

[0099] like Figure 4-Figure 7 As shown, when the solenoid valve drives the push rod upward to drive the lever structure 33 and the lock hook 34 to unlock, the lever structure 33 rotates to a certain angle to push the lock hook 34 open.

[0100] Although the embodiments of the present application have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations shall fall within the scope defined by the appended claims.
